File.Exists does not support the File.DirAssets folder.
File.Exists(File.DirAssets, bmp) will always return false.

You shouldn't use File.Exists with File.DirAssets. The results will not be consistent.

How can I then check if the file exists?

You should know which files were added to File.DirAssets. You added those files.

Log(FileExistAsset("icon.png"))

Public Sub FileExistAsset(FileName As String) As Boolean
    For Each Name As String In File.ListFiles(File.DirAssets)

This code is a part of a library.
Since this library can be used in multiple apps, there is a risk of writing something that is not present in "dirAssets" or is written incorrectly.
Since this error is not noticed right away, it must be seen right away in the menu display. Therefore I show a warning icon to make you aware of the error.

You could create a b4xlib library and include the necessary files in the Files folder.

It is possible to do a similar thing also in a "classic" B4A-jar library:

Copy the asset file to a temporary directory.
The copy fails if the source file is not existent
